After three times to determine what was wrong with my truck. They charged me a premium price to swap out the bad unit. I don't see why after two times of removing the defective unit, cleaning it, reinstalling it, the third time full labor. On a $580 part the final bill was $1,011.00 and change. Wow those are expensive bolts. All three of them that are right on the side of the transfer case. $143 a bolt.... I am getting to old to crawl on the ground to do it. Will be thinking three times before I have them work on a anything that doesn't have a warranty associated with it.
